JOSEPH J. GANNON, OF ST. CLAIR, MICHIGAN, ASSIGNOR TO DIAMOND CRYSTALSALT COMPANY, OF ST. CLAIR, MICHIGAN, A CORPORATION OF MICHIGAN.

CLOSURE.

Application filed June 18, 1923.

To all whom it may concern.-

Be it ,known that I, Josnrr-r J. GANNON, a citizen of the United Statesof America, residing at St. Clair, in the county of St. Clair and Stateof Michigan, have invented certain new and useful Improvements inClosures, of which the following is a specifloat-ion, reference beinghad therein to the accompanying drawings.

This invention relates to closures for pouring apertures in containers,packages and the like.

An object of the invention is to provide the pouring aperture with asimple and efficient closure which, when in closed position, willmaintain the container in substantially sealed condition so that thecontents will not be spilled and which, when in open or partially openedposition, will guide the flow of material in a predetermined directionand thus will prevent any lateral flow.

Another object is to provide a closure which may be easily and quicklyapplied to or removed from the container.

Another object is to provide a closure which may be readily adjusted inthe pouring aperture and which will remain automatically in any adjustedposition.

Another object is to provide a strong and durable construction which canbe manufactured at a comparatively low cost.

With the above and other objects in view, the invention consists incertain novel features of construction as will be more fully describedand particularly pointed out in the appended claim.

In the accompanying drawing Figure 1 is a perspective view of acontainer provided with the closure and showing the same in openposition;

Figure 2 is a sectional View through the closure and adjacent portionsof the cor. tainer showing the closure in closed position;

Figure 3 is a view similar to Figure 2 but showing the closure in openposition;

Figure 4 is a detailed perspective view of the closure;

Figure 5 is an end view of the closure.

Referring now to the drawing in which like characters of referencedesignate corresponding parts throughout the several views, the numeral1 designates a closure far a pouring aperture 2 which is preferablyformed in the top 3 of a suitable container Serial No. 646,185.

l The aperture 2 is preferably of substantially rectangular form and isprovided at its lnner end with an inwardly projecting tongue 5 which isseparated by parallel slits g from the adjacent side portions of the Theclosure is preferably formed from one piece of material and ispreferably provlded with a flat top 7 having parallel substantiallytriangular-shaped wings 8 extendlng downwardly from the side edgesthereof. The inner end of the closure top 7 is preferably pivot-allymounted on the tongue 5, while the outer end is preferably provided withan extension 9 that is adapted to rest upon the top of the container.

To detachably hold the inner end of the closure top in engagement withthe tongue 5 while the closure is applied to the container, I preferablyprovide a pair of parallel tongues 10 which extend rearwardly from therear ends of the wings 8 adjacent to the top 7 and which are preferablyprovided with straight upper edges 11 for engagement with the lowersurface of the top of the container.

The upwardly swinging movement of the closure is preferably limited andfor this purpose I preferably provide a pair of tongues or stops 12which extend forwardly from the forward ends of the wings at the loweredges thereof and which are preferably provided with straight upperedges 1?) for engagement with the lower surface of the top of thecontainer. The straight edges of the tongues 10 are preferably disposedin a plane parallel to the top of the container while the straight edgesof the tongues 12 are preferably arranged at an angle to the top of thecontainer.

The forward ends of the wings 8 are preferably curved as shown at 14 andthe length of the wings, with respect to the pouring aperture in thecontainer, is such that the curved ends of the wings are constantly infrictional engagement with the forward edges of the pouring aperture.With this arrangement the closure will remain in any adjusted position.

When it is desired to apply the closure to the container, the tongues 12are inserted into the pouring aperture so that the aligned notches 15,formed in the forward ends of the wings immediately above the tongues12, will be in alignment with the top. of the container. -The closure isthenmoved forward until the notches receive the outer edge 16 of thepouring aperture, whereupon the tongues 10 may then be moved downwardlythrough the slits 6 until the flat top of the closure abuts the tongue5. The closure may then be moved rearwardly until the inner ends of thewings abut against the ends of the slits 6. The closure may then belowered to closed position as illustrated in Figure 2.

To prevent the closure trombeing accidentally shaken out of the pouringaperture,-the sides of the'notches 15 are preterably arranged parallelto the topof the container. Thus, when the closure is raised, thesenotches will not be in alignment with the top of the container.

"To remove the closure from the. pouring aperture,- the top of thecontainer is depressed slightly at the outer end of the pouringapertureso that the notches 15- will receive the outer: edge 16 of the pouringaperture, whereupon the closure may be moved forwardly to disengage theprojections 10 from the slits 6. The closure may then be movedrearwardly to be'withdrawn entirely from the pouring aperture. 7

WVhile it is believed that from the foregoing description, the natureand advantages of the invention will be readily apparent,

I desire to have it understood that'I do not limit myself towhat isherein shown and described and that such changes may be re sorted towhen desired, as fall within the scope of what is claimed.

l/Vhat I claim as my invention is The combination with a containerhaving a rectangular opening in the Wall thereof and a projecting tonguein said opening separated by parallel slots from the ad jacent sideportions of the wall, of a closure for said opening having atop'pivotally engaged with one end thereof and having parallel dependingsubstantially triangular shaped side wings, pointed projectionsextendingforwardly from said wingsand adapted to engage said container to 'limitthe upward swinging movement of said closure, the lower edges of saidprojections being formed by the rounded upturnof the lower edges of saidwings and the-upper edges of said projections being-disposed-at an angleto said-top, and notches inthe forward ends of said wings witlr'edgesparallel to the top of said closure torapplying the closure to thecontainer,-the lower edge otsaid notches being anangled continuation'otthe upper edges of said projections.

In testimony whereof I affix my signature.

JOSEPH J. GANNON.
